FIELD OF THE INVENTION

The present invention relates to toilet treatment devices, systems and methods, more particularly to an automatic and autonomous water and energy saving devices and methods for cleaning, deodorizing and disinfecting toilets.

BACKGROUND OF THE INVENTION

Toilets and specifically flush toilets are the most common sanitation fixtures used in the western world for disposal of human urine and feces. A typical flush toilet includes a ceramic bowl (pan) connected to a cistern (tank) that enables rapid filling with water and to a drain pipe for removing the effluent.

Naturally, toilets bowls and specifically bowls of public toilets require fundamental and frequent cleaning and sanitization to prevent bacteria growth and contaminations. Traditionally, toilet bowls have been cleaned, deodorized and disinfected by manual scrubbing with a liquid or powdered cleaning and sanitizing agent. In order to eliminate the manual scrubbing, various toilet bowl cleaner dispensers have been proposed.

One of the popular toilet bowl cleaner dispensers include aerosol deodorizing and/or cleaning agent that is dispensed into a toilet bowl through a conduit attached to the toilet bowl rim. Another well-known toilet bowl cleaners examples include automatic toilet bowl treatment devices. Such automatic devices include fluid reservoir, a pump, and a hanger means such that the entire device may be suspended from a part of a toilet bowl.

An example of a Dispenser device is illustrated in US Patent Application No. 2011/0302705 entitled “Dispenser device in particular a we rinser with fixing means” to Frey et al. The application relates to a release device, in particular toilet freshener, for releasing at least one preparation into the interior of a toilet bowl comprising a dispenser, at least one container connected to the dispenser for storing at least one preparation, a release element for releasing preparation, in particular into the interior of a toilet bowl, the release element being connected in communicating manner to the container via a line and the bottom of the container being arranged above the release orifice of the release element in the direction of gravity, such that a difference in level Ah is formed between the bottom of the container and the release orifice of the release element.

Another example of a dispenser is illustrated in US Patent Application No. 2004/0031091 entitled “Toilet rim dispenser for colored liquid” to Landesberg et al. A liquid rim dispenser intended for suspension from a rim of a toilet bowl adjacent a wall thereof, in the path of flushing water during a flushing operation, comprises a basin with a basin wall and a basin bottom having a bottom opening and a cup with a cup wall and a cup bottom fixed within said basin. The dispenser further comprises a container with a colored staining liquid having a discharge opening facing the bottom of the cup with a predetermined clearance therebetween. The dispenser is so configured that the discharge opening is lower than the cup wall, and the bottom opening is lower than the cup wall and is located remote from the wall of the toilet bowl, and at least when the dispenser is suspended from the bowl rim, the bottom opening is higher than a low portion of the basin bottom.

The prior toilet cleaning instruments can be less than ideal in at least some respects. First, the cleaning and disinfection end result of prior cleaning solutions is incomplete leaving uncleaned areas and areas which were not sufficiently disinfected. Specifically, areas which are not in proximity to the cleaning instrument are typically left unclean. Second, known cleaning devices are insufficient requiring multiple washing cycles till the toilet bowl is properly cleaned. As a result, large amount of water and detergent are wasted resulting in non-saving (e.g. ‘non-green’) device and system. Third, prior devices require external energy support such as electricity connection to improve the instrument efficiency. Forth, the cost of prior toilet cleaning instruments can be greater than would be ideal. Fifth, the prior toilet cleaning instruments can be somewhat bulky, difficult to operate and the cleaning instrument parts require professional handling than would be ideal in at least some instances. Six, the prior toilet cleaning methods and devices require permanent human intervention, sometimes every 3 or 4 hours, such as refilling the cleaning containers, and cleaning specific areas which were not sufficiently cleaned by the cleaning device.

It would therefore be desirable to provide an improved, cheap and easily producible and autonomous toilet cleaning device.

It would therefore be desirable to provide a cleaning device not hinging on external power resources.

It would be further desirable to provide improved, and low-cost integrated cleaning toilet instrument that overcomes at least some of the aforementioned problems with the prior art.

FIG. 2A shows a top side isometric view of the devices 100 or 150 of FIGS. 1A-1G hung on a toilet bowl rim 240 in accordance with embodiments. In some cases, the devices 100 or 150 may be suspended from the toilet rim 240 by hanging the bridge unit 120 for example along the surface of a section 225 of the toilet bowl rim 240.

According to some embodiments the device units, such as the bridge 120 are adjustable and configured to be placed or attached to any type or size of toilets.

Specifically, the bridge unit 120 comprises a flat stripe section 122, preferably to accommodate the geometries of different types of toilet bowls and two flexible sections, extending from the flat stripe section, configured to be folded along the inner and external sides of the toilet bowl rim 240. For example, as shown in FIG. 1C, a first flexible section 123 extending from section 122 may be bended in perpendicular or substantially in perpendicular (e.g. between 60-90 degrees) in respect to the toilet bowl rim surface 240 downwardly towards the outer side of the toilet bowl rim surface. The first flexible section 123 may be connected to the storage and control unit 130 and hold the storage and control unit 130 in parallel or below the toilet bowl rim surface 240 as illustrated in FIGS. 2B and 2C. The bridge unit 120 further comprises a second strip section 124 extending from the other end of the flat stripe section 122 downwardly towards the interior of the toilet bowl rim. The second flexible section 124 may be connected and hold the treatment unit 110 preferably below and away the toilet bowl rim 240. As shown in FIG. 2A and further illustrated in FIGS. 5A and 5B a first portion 127 of the second strip section 124 extending from the flat stripe section 122 is bended vertically in respect to the flat section 122 while a second portion 125 extending from the first portion 127 is bended outwards in angle α of between 0-45 degrees in respect to axis Y from the toilet bowl rim to place the cleaning module below and away from the rim 240, for example at the path of the flushing water. Thus, water flushing on the sidewalls of the toilet bowl inner surface during flushing operation will be efficiently accumulated or to at least temporarily will retain a quantity of flushing fluids at the treatment unit 110.

In some cases, as illustrated in FIG. 2C, once the device is positioned on the toilet bowl rim, the device may be covered by the toilet's seat 250 to avoid direct contact between the device 100 and a user.

Reference is now made to FIGS. 3A-3J illustrating a number of isometric views of the treatment unit 110, in accordance with a number of different embodiments.

As illustrated in FIG. 3A, the treatment unit 110 comprises a housing 311 for covering and holding one or more fluid reservoirs such as container 321 placed within the housing. The container 321 is configured to accumulate fluids such as fresh water flushing from the toilet's flush tank via one or more openings or apertures, for example through opening 320.

According to some embodiments the opening 320 may be formed at the top right side of the housing and may have a crescent shape. In some cases, the opening width size may be between 10-30 mm for example 18 mm. In some cases, the opening may have other shapes and size.

The housing 311 may include or may be made of a number of cover parts such as two cover parts 322 and 324 which may be attached to one another according to methods as known in the art (e.g. vacuum pressure, glue, or attachment pins 384 etc.). According to some embodiments, the housing 311 is convexly shaped to enable fluid such as fresh water flushing from the toilet's flush tank to gather and flow into the opening 320 or flush down the toilets.

According to some embodiments the housing may be made of one piece having for example two convexly shaped sides A and B.

The treatment unit 110 further comprises one or more spraying units such as a first spraying unit 360 (e.g. bottom spraying unit) for dispersing cleaning composition and/or fluids such as flushing tank fluids (e.g. fluids accumulated at the container 321). The first spraying unit 360 is configured and enabled to spray the fluids typically with a cleaning composition (e.g. the detergent) all over the interior toilet bowl perimeter according to a number of predetermined intervals till a complete cleaning and sanitization of the toilet bowl is accomplished.

In this embodiment, an external arm 361 is located an elongated groove 399 forming a long narrow channel along the treatment unit 110 length, for example at the center or substantially the of the treatment unit . In some cases, the external pipe is folded and extends out of the housing 311 via opening 361.

In operation, the external pipe rotates out and away from the treatment unit, in perpendicular (e.g. between 0-120 degrees) to the treatment unit length (e.g. X axis) for spreading sanitization material in 360 degrees (all directions) at the entire cavity or substantially the entire inner cavity and outer surroundings of the toilet bowl as illustrated in FIG. 3F.

According to some embodiments, the spraying unit 360 is located at an elongated groove 399 formed (e.g. notched) at the center or near the center of the treatment unit 130.

In some cases, the elongated groove 399 may be formed longitudinally at the outer surface of the housing at side A on the front side of the treatment unit facing the toilet bowl inner surface at the center of the housing around a perimeter, for example at the center, or substantially near the center of the treatment unit 110.

In some cases, the groove 399 may be shaped as rectangle along and within the housing having a depth of 1-40 mm.

For example, as illustrated in FIG. 2A a number of streams (i.e. arrows 241) are directed by the spraying unit 360 all over the interior toilet bowl perimeter to efficiently clean the toilet bowl. According to some embodiments, the elongated groove 399 includes a rail 362 notched along the housing 311 (shown also in FIG. 3G) and one or more nozzles are embedded or coupled within the rail 362 inside the housing 311. In some cases, the one or more nozzles are configured to move back and forth along the rail 362 and/or rotate while spraying cleaning composition to the toilets. In some cases, the rail 362 may be divided to a number of segments and the nozzles may be embedded along these segments. For example, as illustrated in FIG. 3B the spraying unit 360 may include a number of openings such as four openings 361, 363, 365 and 367 formed along the groove 399 for enabling a number of respective nozzles 361″, 363″ 365″ and 367″ located inside the treatment unit housing to spray cleaning materials (e.g. detergent materials) to the interior of a toilet. In some cases, the nozzles are fixed, for example to the rail 362. In some cases, the rail 362 may respectively be divided to three or more sections such as sections 363′, 365′ and 367′ and the nozzles may move back and forth along the segments spraying for example concurrently a number of sections of the toilet bowl.

In some cases, each of the nozzles 361″ 363″, 365″ and 367″ are configured for facilitating dispersion of fluids aggregated in the housing 311 into a spray. The nozzles are used to distribute the aggregated fluids mixed for example with cleaning materials over the toilet bowl area, to increase liquid surface area, and create impact force on a solid surface.

In some cases, the nozzles may be spray nozzles such as solid-cone single-fluid nozzle, compound nozzle and other nozzles as known in the art.

According to some embodiments, the nozzles may move and rotate along the rail by one or more motors such as one or more step motors or by fluid pressure means.

In some cases, the nozzles may move and rotate autonomously without the use of dedicated motor.

In some cases, the nozzles may move or rotate by one or more means configured to move and rotate the nozzles such as one or more springs, fluid pressure means, chemical reaction, air pressure etc.

In some cases, the treatment unit 110 may include a single nozzle which is configured to move along the rail back and forth.

In some cases, the spraying unit may spray the accumulated fluids with or without the cleaning composition (e.g. the detergent) all over the interior toilet bowl

According to some embodiments the treatment unit 110 includes an additional spraying unit 359 configured to spray cleaning materials such as sanitization and/or foaming material into the interior of a toilet bowl, for example simultaneously, in all directions (e.g. 360 degrees) as shown in FIG. 3I. The spraying unit 359 may include, for example, an elongated arm in the form of an elongated cylindrical pipe which may be placed for example in the elongated groove 399. In a pause mode the pipe is hidden within the groove. Once activated the pipe is rotated outward, for example in perpendicular to the treatment unit length axis.

According to some embodiments, the treatment unit 110 length may be between 100 mm to 200 mm for example 170 mm long and height of between 50 mm to 100 mm, for example 71 mm. The cylindrical pipe 361 may be between 50 mm to 100 mm for example 90 mm long and the groove 399 may be for example between 60 mm 190 mm long for example 160 mm long.

In some cases, the fluids include flushing tank fluids, such as fluids aggregated at the container 321 or at the treatment unit 310 cavity mixed with cleaning materials transferred via pipe 371 from the storage and control unit 130 or with cleaning materials such as solid or fluids cleaning materials placed in the treatment unit cavity.

According to some embodiments, one or more external pipes such as the external arm 390 may be attached to the bottom outer side of the treatment unit 310, for example to the outer lower surface 391 of the treatment unit 310 and connected via one or more pipes such as pipe 373 for delivering the one or more materials or compositions, such aerosol and/or disinfection agents from the storage and control unit 130 and spraying the one or more materials or compositions (e.g. aerosol and/or disinfection agents) to the toilet bowl surrounding (e.g. toilet bowl surface, seat etc.).

In some cases, the external pipe 390 may rotate up/down or to the sides along an X-Y or X-Z axis of axis X-Y-Z to efficiently clean hidden locations at the toilets or the toilets surrounding. In some cases, as illustrated in FIG. 3G, the external pipe 390 is configured to rotate between 0-180 degrees in respect to axis Y along surface X-Y using one or more cogwheels 392 and 393 coupled to the motor 395. The motor 395 is configured to rotate the cogwheels 392 and 393 which in turn rotate the external arm 390 for spraying automatically one or more materials or compositions, such as disinfection materials to the toilet bowl cavity and/or specific locations according to one or more instructions received from the processor. In some cases, the external arm 390 may be rotated to the sides/up/down (e.g. 360 degrees) in respect to the treatment unit while one or more materials such as sanitization materials are sprayed to the toilet or to the toilet surface.

In some cases, a spraying unit 396 such as a sprinkler or spray nozzle may be coupled to the distal end of the external arm 390 for spraying the sanitization material upwards (e.g. in the Z axis direction) via one or more nozzles holes to the toilet bowl's cavity or to the toilet's surroundings.

In some cases, as illustrated in FIG. 3I the external arm 390 may be rotated and positioned perpendicular (e.g. between 60-90 degrees) to the treatment unit 310 length, wherein the distal end of the external pipe including the nozzle spray is centered at the toilet bowl cavity for generating and spreading sanitization material 360 degrees (all directions) at the entire cavity or substantially the entire inner cavity and outer surroundings of the toilet bowl.

According to some embodiments as illustrated in FIG. 3H each nozzle may include a spraying head 381 including one or more openings 383 and 385. In some cases, each nozzle may be a compound nozzle in which several individual single or two fluid nozzles are incorporated into one nozzle body. This allows design control of drop size and spray coverage angle. In accordance with other embodiments other type of nozzles may be used.

Reference is now made to FIGS. 4A and 4B illustrating an isometric top and side views of a storage and control unit 430, in accordance with embodiments. Typically, the storage and control unit 430 is externally coupled to the outer side of the toilet bowl, however many other variations and adaptations may be used for placing the storage unit 430, for example inside the toilet bowl or at other locations. The storage unit 430 comprises a housing 410 having for example a first concave side cover 412 configured to be hung in proximity to and in front of the outer side of the toilet bowl and a second compatible side cover 413 which may be convexly shaped. The housing 410 comprises a cavity including for example one or more containers which may be refilled automatically or manually with cleaning and disinfection materials in the form of liquid or powder or solid materials for cleaning and/or foaming and/or disinfecting the toilets.

For example, the housing 410 may include two sealable openings 472 and 474 located at the top sides of the storage unit 430 and may be covered by matching covers 472′ and 474′ which may be used to seal containers 478 and 479, for example by one or more clicking means.

In some cases, the device units, such as the containers 478 and 479 may be easily releasable from the device and inserted back to the device. For example, the containers 478 and 479 may include a frame or other units which can positively engage the body and/or frame to ensure that a suitable seal has been secured and may provide an audible or physical “click” type confirmation.

According to some embodiments, the device comprises one or more power buttons or switches, such as button 425 installed at the storage and control unit 430, shaped for example as a round or square button configured to power the device 100 on and off. Typically, the device powers on when the button is pressed and powers off when the button is pressed again. In some cases, the device may include one or more sensors including voice recognition means for identifying a user command for activating the device on or off. In some cases, the one or more buttons may be positioned on or connected to other units such as the bridge 120 and/or the treatment unit 110.

FIG. 4C shows an isometric view of the units located inside the storage unit 330, in accordance with embodiments. The storage and control unit 430 comprises one or more pumps, such as a first and second pumps 452 and 454, and a circuit board 432 such as a PCB including one or more processing units such as processing unit 431 and memory units 433 and a power source 499. In some cases, the storage and control unit 330 includes a single pipe.

The processing unit 431 is configured to control the device unit for automatically and autonomously cleaning toilets without any human intervention. In operation, the processing unit receives data from the device units including for example one or more indications received from the device units such as the device's one or more sensors and process the data to yield output data for accordingly controlling the device units.

In some cases, the processing unit 431 is configured and enabled to receive movement or pressure indication from said sensors and operate the device spraying units to spray fluids on the interior surface of a toilet bowl according to said sensors indications.

In some cases, the processing device may receive indication of low cleaning material at the cleaning containers or at the cartridges and accordingly update the user to refill the containers or cartridge. In some cases, the processing unit may provide warnings or indications in the form of a “low material” or “low cartridge” status indicator light, or a series of flashing lights that require a user to consult the manual to decipher them.

In some cases, the processing unit may launch a pop-up notification to a user computer screen or mobile device when cleaning toner levels are low.

In some cases, the device comprises a communication module configured to communicate to a server and other units such as speakers to provide information on the unit device status.

In some cases, the storage and control unit 430 may include a container or housing F for holding the power source 499.

Reference is now made to FIGS. 5A and 5B illustrating isometric upper side views of a bridge unit 520, in accordance with embodiments. The bridge unit 520, in some cases, is shaped as an elongated flexible strip which may be hung along the surface of a section 225 of the toilet bowl rim 240 and hold the treatment unit 110 and storage and control unit 130, of device 100 or device 150 or other cleaning devices illustrated herein for example at the sides and below the toilet bowl rim 240. The bridge unit 520 comprises one or more pipes (e.g. pipes 473 and 471) attached for example to the bridge unit 520 surface for delivering and supplying cleaning materials (e.g. aerosol and other agents) and/or fluids to the spraying units such as the first sparing unit 360 and/or external arm 390.

In some cases, the pipes may be made of plastic or other materials as known in the art.

Alternatively or in addition to the pipes, the device 100 may include one or more channels or pipes formed internally as part of the device inner units for supplying treatment materials and/or fluids to the spraying unit 360 or 390. In some cases, the materials may be delivered by air pressure means.

Specifically, the bridge 520 comprises a flat stripe section 522, preferably configured to accommodate the geometries of different types of toilet bowls, and two flexible sections extending from both ends of the flat stripe sections configured to be folded along the inner and external sides of the toilet bowl rim 240. For example, a first flexible section 523 extending from section 522 may be bended in perpendicular or substantially in perpendicular (e.g. between 60-90 degrees) in respect to the toilet bowl rim surface downwardly towards the outer side of the toilet bowl.

According to some embodiments, the distal end 510 of the first flexible section 523 is configured and enabled to slide into the bridge holder 488 and hold the storage unit 130 at the external side and below the toilet bowl rim. It is noted that other methods and configurations may be used to connect the bridge unit 520 to the external and/or the treatment unit.

The bridge unit 520 further comprises a second curved section 524 extending from the distal end of the flat stripe section 522 downwardly towards the interior of the toilet bowl. The second section 524 is configured and enabled to be connected to the treatment module and hold the treatment module below the toilet bowl rim 240.

According to some configurations, the bridge unit 520 may include a second spraying unit 590 (e.g. upper spraying unit) such as an aerosol unit for cleaning and disinfecting the toilet bowl. The second spraying unit 590 may comprise one or more spraying devices such as nozzles, such as nozzle 592 connected via one or more pipes to the storage unit 130 and configured and enabled to spray aerosol into the bowl interior surface.

In some embodiments, the second spraying unit 590 may be positioned at the distal end of the second curved section 524 so as to enable direct spraying to the upper surface of the toilet bowl, for example to the toilet bowl areas which may not be sprayed by nozzles 363, 366 and 369. As illustrated in FIG. 2B and 2C the second spraying unit is configured and enabled to spray cleaning materials (such as streams 244) and/ or disinfection material via a plurality of nozzle on a toilet seat 250 or toilet space.

In some cases, the bridge unit 520 may include one or more indicator units, such as indicator unit positioned at the outer surface of the upper portion 525. The indicator unit may include one or more lights such as LEDs 593, 594 indicating the status of the system (e.g. on or off) or which unit (e.g. upper or lower spraying units) is currently activated.

According to some embodiments, the bridge unit 520 comprises or is connected to electrical generator means, for example, a hydropower unit 540 for producing hydroelectricity to, for example, charge the device's power source, e.g. batteries 499 and thus provide power to activate the device's electronic units for example LEDs 593, 594. The hydropower unit 540 comprises one or more rotating coils of wire such as water wheels to convert mechanical rotation into a pulsing electric current. For example, according to some configurations, the second strip section 524 comprises a ‘T’ shaped portion 526 curving away between 30-60 degrees in respect to the upper portion 525 of the bridge. The ‘T’ shaped portion 526 comprises two arms 542 and 544 extending to the sides from the second strip section 524 and configured to hold one or more electrical generator wheels, such as wheels 545 using respectively pins 569. According to one configuration, as illustrated in FIG. 5C, portion 526 may be attached to the sides of opening 320 of the treatment unit 112 and the wheels 545 may partially or completely be inserted into the treatment unit 112 cavity.

FIG. 5D shows a side view of the water wheel 545, in accordance with embodiments. The water wheel 545 may be octagonally shaped comprising a pivot 561, a number of cavities 566 and blades 567 which are mounted around the circumferential rim of the wheel to prevent the escape of fluids from the ends of the cavities 566 until they have moved a certain distance.

In operation, toilet's flushing fluids are directed via the opening 320 of the treatment unit 112 to the blades of the water wheels, creating a force on the blades. In this way, energy is transferred from the water flow to the wheels (e.g. turbine) producing hydroelectricity in the way water turbine (e.g. Pelton wheel) is operated.

Alternatively or in combination, the wheels, such as wheels 545 may be used as a meter such as a measurement unit for measuring the toilet flush water speed or status (e.g. flushing time) for indicating if the toilet use was completed and the type of use according to the flushing duration. The indications such as the toilet flushing speed and time may be transmitted to the one or more processing unit for activating accordingly the suitable cleaning process. For example, an indication of a short use of the toilets may activate a first cleaning process by for example the cleaning unit 360 for a short period, while an indication of a long use of the toilets (e.g. as a result of indication of flushing for a long period) will automatically activate the rotatable cleaning arm for sanitizing the toilets and/or the cleaning unit for a longer time.

Alternatively or in combination, the device may include other energy generators and motors by way of non-limiting examples these include one or more of: a stepping motor, air pressure means, spring pressure means, chemical reaction mans, mechanical or electrical pressure amplifiers rotary motor or any motor which is configured to activate the system cleaning units such as the system's nozzles or sensors.

According to some embodiment, the bridge unit 520 dimensions may be between 50-130 mm long such as 100 mm at the center section (i.e. the flat stripe section 522) and may extend between 50-100 mm, for example 90 mm at one side (i.e. the second section 524) and between 50-100 mm, for example 60 mm at the other extending section (i.e. section 523). In some cases, the bridge width (i.e. section 522) is around 30-50 mm for example 40 mm.

Reference is now made to FIG. 6 illustrating a flowchart of a method 600 for automatically and/or autonomously cleaning and/or foaming and/or disinfecting toilets, in accordance with embodiments. At step 610 a treatment device such as the toilet cleaning device illustrated in FIGS. 1-5 is provided and initially installed upon a lavatory appliance, i.e. on the toilet's rim. Typically, the device's initial state or ‘default’ state is ‘sleep mode’ where the device is inactivated or in a low power mode. In some cases, for indicating the specific state of the device one or more control lights may be operated, for example one or more lights may light the inner surface of the toilet bowl to indicate the device's mode, for example according to the lights color (e.g. green —‘active’, red—‘inactive’). At step 620, one or more toilet use indications are identified such as movement and/or pressure and/or toilet's color change and/or toilet seat movement and/or voice of one or more users. According to some embodiments, the indications are monitored and identified by one or more sensors, for example by an electronic pressure sensor or distance sensor or by a biologic sensor (e.g. PH sensors), or be a pressure detection sensor such as sensor 119 embedded at the bridge unit 120 for identifying and sensing a pressure or movement of a user such as user seating on the toilet seat or by other types of sensors such as the sensors discussed herein above or other sensors as known in the art. The sensors are configured to identify the specific toilet use and accordingly provide data (e.g. which includes one or more indications) to the processor unit (e.g. processor unit 431) which activate the treatment device 100 based on the received data.

At step 630 the data (e.g. specific indication such as movement, pressure or color, toilet seat movement) is analyzed by the processing unit and thereafter according to the processing output the device state transforms to a ‘ready for activation’ state or back to ‘sleep mode’. At the following conditional step 640 if affirmative, and it is determined by the one or more processing units (which are configured to specifically identify the type of toilet's use based on the sensors indication) that a cleaning process is required then the device transforms to ‘activation’ mode. If an indication was not found, the device mode transforms back to a sleep mode. In some cases, one or more indication lights are switched on to an activation light (e.g. green) and/or a voice hazard is activated according to the identified indication. For example, yellow colored indication for the first cleaning procedure (as illustrated at step 660) and a green color for the second procedure (as illustrated at step 670). At step 650, the device is activated and a cleaning procedure is initiated based on the processed data.

The cleaning process includes, according to some embodiments, the following steps: At step 660 the bottom spraying unit 360 is activated and one or more sparing means such as nozzles 361″, 363″, 365″ and 367″ automatically spray fluids such as fluids which were accumulated and/or stored for example at a container 321 mixed with one or more treatment materials/cleaning agents which were stored at the treatment device (e.g. solid material 387). The spraying may include using pump means such as pump 380. An example of such a spraying procedure is illustrated in FIG. 2A.

In some cases, the one or more nozzles such as nozzle 361″, 363″, 365″ and 367″ automatically move and/or rotate along rail 362 spraying fluid which were stored for example at a container 321 along with one or more treatment materials/cleaning agents which were stored at the treatment device.

According to some embodiments, the treatment materials/cleaning agents may include the following materials sprayed in the following order: a. cleaning and whiting materials b. anti-stick materials c. foamy materials d. coloring materials e. perfuming materials. It is noted that the cleaning procedure may include a use of other materials according to a different order.

The treatment materials may include for example one or more of chlorine, etheric oils, coloring materials, sanitizations materials which include for example clean alcohol or other sanitizations materials, for anti-stick materials a silicon or Teflon materials may be used.

In some cases, the treatment materials are sprayed by water pressure means via the nozzles by water flash which may be reserved for example at the treatment unit container.

In some cases, the cleaning process may last for predetermined time interval of for example 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 or more seconds.

In some cases, the cleaning process may be repeated according to a cleaning matrix, which includes a cleaning procedure as illustrated herein above.

According to some embodiments, the cleaning matrix may be activated according to information or data indications received from the processing unit. The information may comprise images of the toilet or toilet room or toilet area (e.g. toilet bowl or toilet surroundings) or mapping of the toilet area. The processing steps may include a comparison of one or more images of the toilet place (e.g. before and after the toilet use) or comparison of the toilet image to an image reference such as a white color image or other color reference.

In some cases, the matrix may comprise dividing the toilet to a number of sections represented by the cleaning matrix and the processing steps may include identifying one or more specific sections of the matrix sections which require additional or specific treatment according to the identified status of the section. For example, the lower inner part of the toilet bowl may be a first section and the surface around the toilet may be a second section. Once processed (e.g. based on image processing, or RF data, radar data) the cleaning matrix may include data including which type of cleaning is needed for each section.

Specifically, as illustrated in FIG. 2C the toilet, e.g. the interior surface and/or the toilet surrounding may be divided to a virtual cleaning matrix having lengthwise and crosswise lines (x, y, z . . . and 1, 2, 3 . . . ) where each formed rectangle frame defines a section. An image of the interior surface of a toilet bowl including of the virtual lengthwise and crosswise lines may be provided and analyzed and processed by the device (e.g. processing unit) and the identify sections which need specific cleaning such as sanitization or intensive cleaning may be clean by one of the selected spraying units (e.g. 360 or 390) or by one or more of the spraying nozzles 361″, 363″, 365″, 367″ which are in proximity to the identified section which need cleaning. One of the advantages of identifying and cleaning a specific section include energy and water saving as only specific units of the device are operated for predetermined time intervals for cleaning specific locations.

In some cases, the cleaning process may be according to a general cleaning procedure and not according to the cleaning matrix.

At step 670, following the activation of the bottom spraying unit 360 and/or once the first cleaning process is completed (for example after 8 seconds) a second cleaning process is initiated which typically comprises a sanitization procedure. According to some embodiments the second cleaning process is executed by the upper spraying unit 590 or by and/or external arm 390 to spray sanitation materials to the toilet boil cavity and/or the toilet seat and/or to the lavatory space as shown in FIG. 3I, thus providing a complete and optimal cleaning and sanitation result in minimum time.

It is noted that the first cleaning process (step 660) and/or the second cleaning process (step 670) is typically initiated once the sensors (such as the proximity sensors) confirm that the user or any person is not at the vicinity of the treatment device 100, for example, based on an indication of a movement of the toilet seat or other indications confirming that the user toilet's use is completed. Additionally, the second cleaning process (step 670) which comprises one or more sanitization procedures is activated once an indication is received confirming that the user or any person is no longer in the lavatory (for example for health reasons).

In some cases, the one or more indications such as the user movement, voice, color or the toilet seat movement are categorized and/or prioritized for example by the one or more processing units (e.g. processing unit 431 or 810) to provide secured and healthy cleaning process and avoid injuries to the user, for example the toilet seat movement indication is a secondary indication while the user movement is a substantial indication.

According to some embodiments, the cleaning device comprises different treatment programs for women and men toilets. For example, for women toilets the indications and treatment program are according to women use while for men toilets the indications and treatment program are based on men use. Based on the one or more indications the treatment device is configured to indicate in real time the exact toilet use.

Optionally at step 680 a third cleaning process which may be automatically and/or cyclically activated, for example, each hour once the indicators confirm that there isn't any person in proximity to the toilets or the treatment device. The third cleaning process may include disinfection of the toilet seat or toilet's space for example by the upper spraying unit 590 and/or external arm 390 or other spraying units or nozzles. Specifically, the disinfection comprises spraying a sanitizer which may volatilize in less than for example few seconds followed by perfuming the toilet surroundings (e.g. the toilet bowl).

In some cases, the first and/or second or any cleaning process may be autonomously stopped or repeated according to indications received by the one or more sensors of the device or by external indications received at the processing unit. For example, the proximity sensor may send an indication that a user is still at the vicinity of the toilet and therefore the processing unit will block any cleaning procedure or a cleaning procedure that might risk the user. Alternatively or in combination the processing unit may operate a cleaning procedure which will not risk the user (e.g. using only clean water). Alternatively or in combination, the processing unit may receive data, for example by the communication module not to clean the toilet and to obtain samples.

FIG. 6B is a flowchart of a method 690 automatically and/or autonomously cleaning and/or foaming and/or disinfecting toilets, in accordance with embodiments. At step 691 a treatment device such as the toilet cleaning device illustrated in FIGS. 1-5 is provided and initially installed upon a lavatory appliance, i.e. on the toilet's rim. At step 692 a pressure sensor, such as a pressure sensor configured to identify or be activated once contact or pressure on the device 100 or 150 is activated, for example, be an object's pressure, such as a toilet user pressure. At step 693 the device is activated as a result of the pressure identification. At step 694 a timer or a processing unit activates the device for a predefined time and a first cleaning procedure is activated, including for example cleaning dirt using toilet flushing water mixed with cleaning material. In some cases, the cleaning procedure may be activated by the first cleaning unit 360 which accordingly activates the sparing nozzles for cleaning the interior of a toilet. In some cases, the timer may be tuned differently for men's toilets and to women's toilets, e.g. for a short period time of 5-10 seconds for men's toilets. At step 695 a proximity sensor may identify that a user or that an object is no longer at the toilet vicinity and at step 696 a timer or the processing unit may accordingly activate a second cleaning procedure by for example the rotating arm for sanitizing the toilet as illustrated for example in FIG. 3I.

FIG. 7 is a flow chart illustrating in details a process 700 of operating the cleaning devices 100 or 150, in accordance with embodiments. Prior to the device activation the device is typically in sleep mode 710 where the device's units are not operated or on energy saving mode. At step 720 one or more indication lights or speakers provide information of the device's status (e.g. according to the indicator light color, or upon pushing a status indication button), confirming that the device will not be activated. In some cases, at step 730 the device may periodically operate an automatic check of the device's cleaning material status. Accordingly, the material containers may be automatically filled via one or more dedicated pipes and pumps connected to an external or an internal tank. Alternatively or in combination, the device's containers may be filled by a user. At step 740 the device's mode is transformed from ‘sleep’ mode to ‘ready for activation’ mode once the one or more sensors such as the proximity sensors indicate at step 750 a use of the toilets or a number of water flushing cycles. Accordingly, at step 760 lights or speakers indicate the device is in ‘ready to activate’ mode and at step 770, once the sensors confirm that that the user is no longer in proximity to the toilet bowl seat or the user completed using the toilet's the device's processor automatically activates the device at step 780 to initiate a cleaning process as illustrated in FIG. 6. For example, once the user stands or flush the toilet the first cleaning process is activated and once he leaves the toilet, the second cleaning process is activated.

FIG. 8 is a high level schematic block diagram 800 illustrating elements of the cleaning device such as device 100 or 150, according to some embodiments. The device 100 comprises one or more processing units 810 configured and enabled to operate the device according to one or more inputs or data received for example from one or more sensors, such as sensors 820. The sensors 820 may be attached or coupled for example to the bridge unit 120 and/or to treatment unit 110 and/or the storage unit 130. Alternatively or in combination the sensors 820 may be external to the device 100 for example in proximity to the toilet bowl or at one or more locations in the lavatory.

In operation, the one or more sensors 820 such as a proximity sensor 880 or a pressure sensor 870 or Biological/Chemical sensors 875 are in communication with the processing unit 810 to operate the device 100 according to one or more specific sensing indications. For example, the pressure sensor 870 may provide data which recognize that the toilet is still in use and accordingly update the processing unit 810 analyze the received data and prevents the activation of the device (e.g. prevents initiation of a cleaning process). The processing units 810 are continuously updated (e.g. in real-time) with the information and data received from the sensors and once a change such as pressure and/or movement and/or any change is measured by the pressure sensor and/or based on additional indications such as information received from the proximity sensors a cleaning process may be initiated as illustrated in FIGS. 6 and 7.

According to some embodiments, the processing units may be in communication with one or more imaging units 878 or other sensors for analyzing and diagnosing images or samples obtained by one or more sampling devices 816 such as tubulars.

Additionally or alternatively the processing units may operate and control the cleaning device according to a predetermined cleaning matrix 815 which includes the device's operation rules for controlling and monitoring the device cleaning operation. The operation rules may include, for example, conditions for operating the device, time lines, and specific type of cleaning procedures to be operated by the spraying units (e.g. upper or lower spraying units) according to the toilet's condition or cleaning matrix. In some cases, the matrix 815 may include data, provided for example by the sensors 820 in real-time, relating to specific toilet bowl's locations which require further cleaning and/or sanitization. The data may be further analyzed by the processing unit 810 which accordingly activates the appropriate spraying unit (e.g. the upper or lower spraying unit).

In some cases, the device 100 may receive information from external devices such as client devices 818, via a server network including data relating to the toilet status or commands to activate or deactivate the one or more sensors and/or imagers and/or cleaning units via a communication module 817.

The client devices may comprise, for example, desktop, laptop, or tablet computers, media consoles, personal digital assistants or smartphones, or any other sort of device with the types of network, video and audio interfaces and computing capabilities needed to interact with the network server. By way of example, the device may comprise a computer with a processor, memory, display, a user interface configured to receive a navigation command from a user, a communication module configured to communicate with the server and other units such as speakers. In some cases, the devices may be for example a mobile phone comprising a processor, display and memory.

Once a cleaning process is operated one or more indicators 831 show the device's status for example by one or more light colors 832. Specifically, a green color may indicate that the device is currently operating a cleaning process while a red color may indicate the device is in sleep mode. Alternatively or in combination, one or more speakers 834 may announce the device's cleaning operation such as ‘cleaning’ ‘sanitization’ etc.

The cleaning process as illustrated herein above in respect to FIG. 6 may comprise pumping fluids from the fluids container and spraying by pressure the water to the toilet bowl surface. Additionally, cleaning materials 802 are derived by one or more pumps 804 via one or more pipes from containers 803 located for example at the external unit or at other units such as the bridge, to the spraying unit 806. Once approved by the processing units 810 the cleaning materials 802 are sprayed via the nozzles 812 into the toilets. The spraying procedure is controlled by the processing unit by one or more motors 814 configured to rotate and move the nozzles 812 or external sparing arm 890 to spray the cleaning material 802 at specific locations such as inner toilet surface locations which require additional cleaning.

A person of ordinary skill in the art will recognize variations and adaptations that may be made to the flow as shown in FIGS. 6-8, including, but not limited to, the removal or addition of one or more components, one or more components arranged in a different order, and/or one or more components comprising subcomponents of other components.

In accordance with embodiments, the device units (e.g. device 100 or 150) such as the pumps, sensors, spraying units include communication elements or means such as wireless or wired circuity for communication with each unit and specifically with the processing unit (e.g. processing unit 431) for receiving instructions from the processing unit to be operated according to the data received from the one or more sensors.

In accordance with embodiments, the device is configured to operate with IoT hub.

In some cases the IoT hub may comprise a WAN interface to couple the IoT hub to an IoT service over the WAN, and a local communication interface to communicatively couple the IoT hub to a plurality of different types of IoT devices; and at least one IoT device having a memory for storing program code and a microcontroller for executing the program code, wherein the program code includes library program code comprising basic building blocks usable by a developer to implement any IoT device by creating application program code which utilizes the library program code, wherein at least one of the basic building blocks comprises a communication stack to enable communication with the IoT hub, the library program code provided to the developer in a software development kit (SDK) with the microcontroller as illustrated in U.S. Pat.
